Available in PDF, EPUB and Kindle. Book excerpt: The world of today must face up to two contradictory energy problems: on the one hand, there is the sharply growing consumer demand in countries such as China and India. On the other hand, natural resources are dwindling. Moreover, many of those countries which still possess substantial gas and oil supplies are politically unstable. As a result, renewable natural energy sources have received great attention. Among these, solar-cell technology is one of the most promising candidates. However, there still remains the problem of the manufacturing costs of such cells. Many attempts have been made to reduce the production costs of conventional solar cells (manufactured from monocrystalline silicon using diffusion methods) by instead using cheaper grades of silicon, and simpler pn-junction fabrication. That is the hero of this book; the heterojunction solar cell.

Available in PDF, EPUB and Kindle. Book excerpt: This book is composed of 6 papers. The first paper reports a novel technique for the selective emitter formation by controlling the surface morphology of Si wafers. Selective emitter (SE) technology has attracted renewed attention in the Si solar cell industry to achieve an improved conversion efficiency of passivated-emitter rear-contact (PERC) cells. In the second paper, the temperature dependence of the parameters was compared through the PERC of the industrial-scale solar cells. As a result of their analysis, PERC cells showed different temperature dependence for the fill factor loss as temperatures rose. The third paper reports the effects of carrier selective front contact layer and defect state of hydrogenated amorphous silicon passivation layer/n-type crystalline silicon interface. The results demonstrated the effects of band offset determined by band bending at the interface of the passivation layer and carrier selective front contact layer. In addition, the nc-SiOx: H CSFC layer not only reduces parasitic absorption loss but also has a tunneling effect and field-effect passivation. The fourth paper reports excimer laser annealing of hydrogenated amorphous silicon film for TOPCon solar cell application. This paper analyzes the crystallization of a-Si:H via excimer laser annealing (ELA) and compared this process with conventional thermal annealing. The fifth paper reports the contact mechanism between Ag–Al and Si and the change in contact resistance (Rc) by varying the firing profile. Rc was measured by varying the belt speed and peak temperature of the fast-firing furnace. The sixth paper reports a silicon tandem heterojunction solar cell based on a ZnO/Cu2O subcell and a c-Si bottom subcell using electro-optical numerical modeling. The buffer layer affinity and mobility together with a low conduction band offset for the heterojunction are discussed, as well as spectral properties of the device model.

This book was released on 2011-11-16 with total page 588 pages. Available in PDF, EPUB and Kindle. Book excerpt: Today’s solar cell multi-GW market is dominated by crystalline silicon (c-Si) wafer technology, however new cell concepts are entering the market. One very promising solar cell design to answer these needs is the silicon hetero-junction solar cell, of which the emitter and back surface field are basically produced by a low temperature growth of ultra-thin layers of amorphous silicon. In this design, amorphous silicon (a-Si:H) constitutes both „emitter“ and „base-contact/back surface field“ on both sides of a thin crystalline silicon wafer-base (c-Si) where the electrons and holes are photogenerated; at the same time, a-Si:H passivates the c-Si surface. Recently, cell efficiencies above 23% have been demonstrated for such solar cells. In this book, the editors present an overview of the state-of-the-art in physics and technology of amorphous-crystalline heterostructure silicon solar cells. The heterojunction concept is introduced, processes and resulting properties of the materials used in the cell and their heterointerfaces are discussed and characterization techniques and simulation tools are presented.

This book was released on 2016 with total page 211 pages. Available in PDF, EPUB and Kindle. Book excerpt: Crystalline silicon is the dominant technology in the rapidly-growing photovoltaics (PV) industry, but significant cost reduction is still required before widespread grid parity is achieved. One-quarter of the cost of a PV module is the Si wafer. One way to reduce the cost/kWh of PV is to identify a higher-efficiency "drop-in" substitute for the currently dominant p-type multicrystalline silicon (mc-Si) wafer. This thesis explores one class of wafer substitute: n-type silicon. This material is thought to have higher defect tolerance than p-type, but practical mc-Si cell efficiencies have remained lower than in p-type. This thesis explores why, using a combination of simulation and experiment. In particular, synchrotron-based micro-X-ray fluorescence mapping is used to non-destructively evaluate metal impurity evolution during processing. This thesis demonstrates that metal impurity redistribution during solar cell processing is similar in n- and p-type mc-Si but the relative electrical impact of point defect and precipitated impurities is different, requiring different approaches to processing. It has been hypothesized and shown indirectly that metal impurities redistribute similarly in n- and p-type mc-Si during processing. To confirm this hypothesis, I combined Fermi-level analysis with direct measurements of the metal distribution before and after an industrially-relevant range of gettering processes. This study confirmed that the understanding of metal redistribution developed for p-type mc-Si is directly applicable to n-type mc-Si. To improve the understanding of metal impurity movement during solar cell processing, I developed a tool using Sentaurus TCAD software to visualize in 2D metal redistribution and the resulting recombination activity. I also performed an analytical review of the state of the art of crystalline silicon solar cell process simulation tools. The analysis elucidated the key physics of impurity gettering during solar cell processing and enabled guidelines for efficient, yet accurate, solar cell process simulations. To quantify the recombination activity of precipitated iron in n-type crystalline silicon, I directly measured the iron content and recombination strength of iron precipitates in n-type crystalline silicon using a suite of micro-characterization tools. I found that iron-containing precipitates are highly recombination active in n-type Si and that the precipitate size is correlated with its recombination strength. To enable this study, I benchmarked the use of a new high-throughput synchrotron-based data collection mode called on-the-fly scanning. To bring the level of sophistication of predictive simulation for p-type mc-Si to that of n-type mc-Si, I developed a simulation tool that calculates the redistribution of iron throughout the solar cell process and the resulting injection-dependent electrical performance of the wafer for both p- and n-type Si. Analysis using this tool indicates that p-type mc-Si usually requires point defect remediation during a slow cooling process, but for n-type mc-Si, dissolving iron-rich precipitates during shorter, higher temperature processing is often sufficient. Efficiency entitlement curves predict that n-type mc-Si can support 20% efficient solar cells. Finally, knowledge of defects developed for Si wafers was applied to a key challenge facing the PV industry at the PV system level. In the field, degradation of next-generation industrial p-type mc-Si PV modules has been observed. Leveraging the fundamental understanding of the physics of impurities in Si wafers, the recombination parameters of the root-cause defect were quantified. Building on the rich literature of p-type multicrystalline silicon, this thesis enables predictive engineering of all crystalline silicon materials from wafer growth to module performance in the field.
